It was shown in [1]} that a generative classifier
(a PBN) can compete with state of the art discriminative classifiers.
This seems to contradict the widely-held belief that the
generative task is much harder, and unnecessary for classifying [2]}.
However, generative models are useful in their own right, and
can be applied in some tasks where discriminative classifiers
cannot [3]}. A generative classifier than
can perform as well as a discriminative classifier,
is highly desireable.
